Описание
A stack-based buffer overflow was found in rpcbind's rpcinfo utility. In rpcbdump() short mode (used by rpcinfo -s), version numbers from a remote RPCBPROC_DUMP reply are written into a fixed-size stack buffer without bounds checking. A user or administrator who runs rpcinfo -s against a malicious or compromised rpcbind endpoint could experience a crash or denial of service of the rpcinfo client.
Отчет
Moderate. This client-side vulnerability in the rpcinfo utility requires a user or administrator to execute rpcinfo -s against a malicious or compromised rpcbind endpoint. Exploitation can lead to a client crash and denial of service for the rpcinfo process.
Меры по смягчению последствий
To mitigate this issue, avoid using the rpcinfo -s command against untrusted, attacker-controlled, or compromised rpcbind hosts. Restrict the use of the rpcinfo utility to trusted internal endpoints or secure test environments only.
